Scientists discover giant virus with record-breaking 2.3-micrometre tail:

Researchers have identified a marine virus, named PelV-1, with the longest known viral tail, measuring up to 2.3 micrometres. Discovered in the Pacific Ocean, PelV-1 infects marine phytoplankton and carries a complex genome that includes genes for metabolism and light-harvesting. This finding sets a new record in virology for appendage length and adds to the understanding of virus evolution in marine ecosystems.
